Question

The snowfall for each day of a school week was: 3 inches, 1 inch, 1 inch, 7 inches, and 3 inches. Lisa said that the mean snowfall could be found by adding 3+1+7 inches, and then dividing by 5. Was she correct? Explain.

Answer 1

No bc Lisa didn’t add all of the numbers together. When finding the mean you add all numbers together then divide by how many numbers you have.
